T @ZZ whom it may concer/t:

13e it known that I, FRANK E. hnnee, of N ew VYork city, in the countyand State of New York, have invented a new. and Improved Pencil-Pointer,of which the following is a full, clear, and exact description.

My invention relates to an improvement in pencil-pointers, and has forits object to provide a machine capable of rapidly and perfectlypointinga pencil of any description and of producing a point thereon aslong as may be desired.

Another object of the invention is to construct a machine capable ofpointing pencils expeditiously, and also capable of being convenientlymanipulated.

A further object of the invention is to construct the machine in anexceedingly simple and economic manner. y

The invention consists in the novel construction and combination oftheseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanyingr drawings, forming a part ofthis speciiication, in which similar figures and letters ot' referenceindicate corresponding parts in all the views.

Figure lis afrontelevationol' the machine. Fig. 2 is a partial verticalsection through the body of the machine, the grinding-disk anddrive-wheel being in edge view. Fig. f3 is a vertical section throughthe pencil-clamp and a front elevation' ot' the body of the machine,theV driving-wheel and grinding-disk being removed. Fig. 1 is a sideelevation of the grinding-disk. Fig. 5 is an enlarged vertical sectionthrough the pencil-holder, and Fig. U

's' a section taken practically on the line C f5 Iii lg. 3.

The body or casing A of the machine is mounted upon a base .I3 of anyapprovedeonstruction, and the body or casing consists o l a face-plate10, the upper portion of which is more or less cylindrical, the lowerportion heing somewhat tapering or wedge-shaped, and a marginal flange1i,cxtcnding around the top and side portions ol' the plate to anengagement with the base. In the upper ccntral portion of the Ilange llof the body an `is best shown in Fig. 3.

opening 12 is made, and adjacent to that opening upon the outer face ofthe flange a pinion 13 is pivoted. Upon the inner face of the plate ofthe body, immediately below the opening 12 therein, a socket-plate 14 islocated, being rigidly secured to the body, as This socket-plateprovided with a conical vertical bore 15, eX- tending from top tobottom, the bore being visible from the front ofthe socket-plate, asthat portion of it is conically eut from top to bottom, as shown inFigsf and 6. IThe taper of the bore 15 corresponds to the taper of aproperly-sharpened pencil, and the outer face of the socket-plate isbeveled from the top downward, the upper line being indicated at a, inFig. 6, and the lower line at a,'

and in the front or outerface of this socketplate a series of transversegrooves or channels 16 is produced, adapted as conduits for the dustcreated by the sharpening of the pencil. l

In addition to the casing a drive-wheel 17 is employed. attached crank18, whereby it is rotated. rlhe inner face of the Wheel is provided withteeth 1), beveled so as to mesh with the pinion 13, and the spokes 20vof the wheel are carried inward and are made integral with a disk 21,the in ner face of which disk is beveled from its center in direction ofits periphery,- as shown in Fig. i2, and upon the beveled surface of thedisk a correspondinglyshaped strip 2 ot sandpaper, einery, or othermaterial of an abrading character is adapted to be secured by glue,cement, or otherwise, the attachment between the grinding material andthe disk being so made that one may be removed from the other when thegrinding material has become damaged, so that othermaterial may besubstituted for that worn out. 'lhe bevel of the inner face of the disk21 and the bevel of the outer-face of the socket-plate 11 is the same,as is also shown. in Fig. 2, as

This wheel is provided with an the surface of the disk carrying thegrinding IOO Y of this cup is iade somewhat concaved, inv

sists of a tube 26, having 'a threaded upper end and provided with ahead 27, the lower end o f the tube being made tapering or split',forminga chuck-section 28. The thread upon thetube 26 is exteriorlyproduced and is pref-` erably a left-hand thread, as it is adapted toreceive a socket29, the upper portion of which socket is threaded toreceive the thread upon the tube, while the lower portion of it isreduced in such manner that when 'the sleeve or socket is screwed uponthe tube the jaws of the chuck-section of the tube are'forced.

inward to clamp any articleY placed between them, the pencil 30 to besharpened being passed down through the tube and out between the jaws atthe lower end of the tube. The sleeve 29of the clamp has a beveledpinion 31, produced upon its outer face, and this beveled pinion isadapted to mesh with the pinion 13 upon the body when the lower end oftliesleeve has been entered into the opening 12 at the top of the body,as shown in Fig. 3.,

In order that the dust from the pencil as it is being sharpened maybeprevented from dropping uponthesupport a cup 32 `is located within thelower portion of the body A, be

ing attached in any suitable' mannereitherv to the base orto the body.The upper face order that itmay lit snugly in the bodyand yet admit ofthe revolution of the drivewheel17. In theioperation of the-pencilpointer or 'Sharpener the pencilis placed in the vclamp beingI passeddownward through the tubesection 26 of the clamp, an'd the end to besharpened is made to extend a predeterinin'ed distance beyond the chuckend ofthe tube; as shqwn in Fig. 3.. Before this is done the sleeve 29ispartially unscrewed from the tube-scction'of tim clamp, so as to admitof the-jawsof the latter being opened; but after the pencil has beenplaced in position the sleeve-isscrewed upward upon the tube-section,closing the `)aws of the chuck portion ofthe -tube around the pencil.The lower end of the sleeve-of theclamp is now passed into the opening12 at the top of the casing, and the gear` l31 upon fthe-sleevewillengage '.-with the bevel-gear 13 of the body, and by exerting downwardpressure upon the head 2"? of the clamp and turning the handle 18,

attached to the drive-wheel 17, the latter will revolve-the clampthrough the medium of' the'pinion 13, and will also turn the diskcarrying the abrading material, and this material, being brought inyconstant engagement while revolving with that portion of the wood andlead'of the pencil exposed through the vertical cut in the socket-plate,will sharpen the pencil, give it the proper shape, and taper the woodabove the point, and this Ais especially so as the pencil while beingsubjected 4to the action of. the abrading material isalso revol 'edfThis device is simple, durable, and economic, and is capable of beingoperated succes'sfully by any person. As the material `is, rubbed fromthe pencil during the process of sharpening, it passes-olf through thechannels A16 in the' socket-plate 'and drops downward into the cup 32.l.

Having thus described my invention, I claim as new and desire'to secureby Letters Patent- I 1.
